To all whom "it may concern:

Be it known that L'HARRY EINE REP- Loonn, of the city of Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in Demount able lVheel-Rims; and l ,do hereby declare that the following is a full, clear, and exact My invention relates particularly to tachable rims of automobile wheels` in which a f metal band encircling the elly has angular recesses formed in the periphl ery thereof and the rim has Aon its inside surface lugs to enter such recesses and bev l locked therein and the objects of m'yfiimprovements 'are first and mainly to secure by means oi" a locking key of special formation, not only the necessary locking in place of the rim after it has been located in .position buhthe tight wedging home 'of the interlockinga lugs and a desirable radial wedging connection between band and rim,

and'secondly, to simplify the form, construction and combination of partsrequired to carry-out the main object vof my invention.

The invention consists of the combination and particular construction of parts hereinafter disclosed and pointed' out in the claims.

F or Afull comprehension, however of the invention reference must be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate the same parts and wherein- Figure l is a side elevation of telly and rimot a vwheel with my invention applied thereto; Figs. Q'and 3 are detail and transverse sectional views of the telly and rim with the key in locking position and taken on lines A A and B B respectively Fig. 5; Fig-l is a detail plan view of a section of the metal band encircling the felly and illustrating the recess therein; Fig. 5 is adetail longitudinal sectional view taken on .line C C Fig. (3; llig. (3 is a detail horizontal sectional View taken on line -D D Fig. .5; and Fig. 7 is a detail perspective vieWo' the key and its carrier. v

The wheel has a telly which, as illuslrated at l), is of the usual oblong rectangular torni in cross section and carries a sur-- roundingmetallic band cl. This metallic hand l has a series oi recesses-'of T-form' in its outer j'ierimeter,n the portion e of each. recess being disposedtransversely te de-V the band and the portion gk circumferentially, the Wall it 'of the portion e being preferablyY ofr angular form with its apexv in the middle, and the bottom of this same portion of -the recess sloping from the center to either end asishown at' c in Fig. 2, thus presenting a through passage of double wedge form- (having wedging, properties oth 'radiallyv and' circumferentially) in .order to permit-'Wedging lkey,*hereafter described, to lloc. entered ateither side of the Wheel and exert a wedging force` in two directions. as above mentioned, while the sides othe circumferential recess portion g converge syinnietrically in a direction awa-y from 'fthe transverse portion eand terminate ina rounded end e.

The wheel rim .lq-.of the usual form to receive and retain the 'tire (not shown), carries 'rigidly a series of lugs m projecting :from the inner perimeter thereof, each lug tapered symmetricallyL throughout its length toward one end, rounded as at m', and having its opposite endm2 inclined in opposite directions from its center and suiieiently Wide to enable the lug to become "tightly wedged in said circumferential porbeing sufficient slaekness between the parts to permit this assembling to be readily done Without the use of any tools, the subse- 'uent drivinghome and tightening yup of t e parts being accomplished by the lock- '.ing key as will now be described.

As a means for forcing the Wedging'lfugs tightly into the circumferential' portions of the recesses. establishing a tight connecvso tion radially between the band and the rim and retaining the part-s inI their locked position-I provide a series of segmental plates t having locking or wedging keys s formed integral therewith and projecting laterally from one side of same to enter the trans-- 'verse portions e oli the recesses in the hand in a circumferential portion of a recess; a 3C f7T and such keys being tapered hoth horiseries of segmentalplates having Wedglng conially and vertically not only serve to eni keys projecting laterally from one side ot d the projecting ends of the lugs and saine to enter the transverse portions of the 5 .torce theln tightly into the circumferential recesses and force said lugs into the circumnnrtions ol? the recesses (retaining them in :terential portions thereof, and means for 35 place when so positioned) but 'also act radiA securing said plates to the side of the telly, elly lo tighten the rini upon the hand.
